A catheter assembly, comprising a catheter [10] having a distal end and an opposing proximal end [14], wherein a longitudinal axis extends between the distal end and the proximal end, and a connector coupled in fluid communication to the proximal end of the catheter. The connector [20] comprising a base [24] extending along the longitudinal axis and including a flange [28] extending in a perpendicular direction relative to the longitudinal axis, the base comprising a sensor assembly having at least one sensor, the at least one sensor configured to sense one or more environmental characteristics at an access site and generate at least one signal representative of the one or more environmental characteristics. An electrical lead wire operatively coupling the at least one sensor to an external device, wherein the electrical lead wire terminates at a contact point [46] molded into or formed on a distally-facing surface [58] of the flange, wherein the contact point is configured to transmit the at least one signal received from the at least one sensor to the external device. In addition to or as an alternative to the electrical lead wire, the connector device may include an optical coupling or channel in the connector configured for optical light transmission between the connector device and the external device.
